What is CNC Turning ?
CNC turning creates axis-symmetric parts by rotating the workpiece while stationary tools remove material; with live tooling, we can add flats, slots and radial/axial holes in one setup. It’s ideal for shafts, bushings, spacers, fittings, valve parts and threaded components.
CNC Turning with KaiSpeed
KaiSpeed machines metal and plastic turned parts in days, from single-piece prototypes to stable production runs. Our engineer-led team operates CNC lathes and mill-turn centers with live tooling, so axial/radial holes, grooves, slots, flats, and OD/ID threads can be completed in one setup for better accuracy and speed. We focus on tight-tolerance cylindrical geometries with high repeatability, backed by practical DFM feedback, consistent process control, and coordinated finishing. Whether you’re launching a first build or scaling a global program, KaiSpeed delivers reliable lead times, solid quality, and competitive pricing for your CNC turning projects.
| Description | |
|---|---|
| Maximum Part Size | Typically up to 500 mm in diameter and 1500 mm in length, though larger sizes can be accommodated with specific equipment. |
| Minimum Part Size | As small as 1 mm in diameter, depending on the material and machining setup. |
| General Tolerances | Standard tolerances of ±0.01 mm; tighter tolerances down to ±0.005 mm can be achieved based on the material and complexity of the part. |
| Lead Time | Standard lead times range from 3-7 days for small batches. Expedited services are available, reducing lead time to 24-48 hours depending on part complexity and material availability. |
Applications
KaiSpeed uses CNC turning to manufacture precision components where concentricity, surface finish, and repeatable fits are critical. Typical parts include:
Shafts & Axles
Motor/gear shafts, spindles, couplers—tight bearing and seal fits with clean lead-in chamfers for assembly.Bushings & Sleeves
Plain/press-fit bushings and liners—controlled IDs and smooth finishes for low friction and long service life.Spacers, Standoffs & Collars
Consistent thickness and parallel faces; deburred edges for safe handling and quick assembly.Pins & Dowels
Locating, clevis, hinge pins—precise diameters for snug alignment; heat-treated steels available on request.Threads & Fluid Fittings
Adapters, glands, ferrules, connectors—OD/ID threading (Metric/UN, pipe threads, etc.) with proper reliefs and gauge inspection.Flanges & Valve Components
Pump/valve flanges, stems, seats—flat, leak-tight faces and accurate groove profiles for reliable sealing.Rollers & Wheels
Conveyor and guide rollers—controlled runout and diameter uniformity for smooth motion and reduced wear.Knobs, Dials & Hardware
User-facing components—repeatable dimensions and clean cosmetics; engraving/marking via live tooling when needed.Housings, Caps & Barrels
Round enclosures, end caps, optical/camera barrels—ports, flats, and slots completed in one setup to limit stack-up.Micro/Long-Slender Parts
Swiss-type turning option for small diameters or high L/D features requiring maximum support.

CNC Turning Case
FAQs
Turning spins the workpiece while tools cut; milling spins the tool while the workpiece is stationary. Turning excels at cylindrical/rotational parts and round features; milling suits prismatic shapes.
Axial/radial drilled holes, flats/slots, light pocketing and engraving—often in the same setup as the turning op, improving accuracy and cycle time.
Typical commercial tolerances for turned parts are tight and consistent; tighter tolerances on critical features are available depending on geometry/material. Share your print and we’ll confirm the achievable spec and gauge plan.
Most engineering metals and plastics; common finishes include anodizing, passivation, plating, black oxide, bead/shot blasting, polishing and heat treatment.
